TOOTH-HOLDER FOR SULKY HAY-RAKES.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed July 9, 1913. Serial No. 778,018.

To all whom it may concern Be it known that 1, JAMES MACPI-IAIL, acitizen of the United States, residing at Davenport, in the county ofScott and State of Iowa, have invented certain new and usefulImprovements in Tooth-Holders for Sulky Hay-Rakes, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to means for holding in place on a rake-head theheavy wire teeth of the rake.

The object of the invention is to provide a holder that can be formedreadily and cheaply from a single sheet of metal; that will be verystrong and durable and that, while holding the teeth very securely, willpermit the laterals or turned upper ends of the teeth to slightly rockas required when the teeth are forced to give or oscillate on account ofmeeting obstructions. I ac complish these objects by the construction ofholder shown and hereinafter particularly described. That which Ibelieve to be new will be set forth in the claims.

In the drawings,Figure l is an elevation of my improved tooth-holdersecured in position to a rake-head and showing also the upper parts ofseveral rake-teeth secured in place by said holder; Fig. 2 is anenlarged vertical section through the devices of Fig. 1; and Fig. 3 isan enlarged perspective view of the holder, looking toward the innerface thereof.

In the several figures of the drawing in which corresponding parts areindicated by the same reference letters: A and A indi cate the twowalls, respectively, of an angleiron rake-head.

B indicates my improved tooth-holder which is formed from a single pieceof metal made in the shape of a channel, the back wall of which isindicated'by b and the upper and lower flanges thereof by 0 and cl,respectively, the said lower flange cl being substantially at rightangles to the back wall I) while the upper flange c is turned sharplydownward so as to bring its free edge nearly opposite the longitudinalcenter of the back wall I), for a purpose hereinafter explained.

e indicates a number of notches in the inclined flange c and inalinement therewith are notches f in the other .flange cl, such notchese and-f being provided to receive the rake-teeth. For convenience inconnecting and disconnecting the rake-teeth several of the holders areemployed placed end to end across the rake and each holder, as stated,is adapted to secure in place a number of the teeth, and as such numberof teeth varies according to circumstances or the ideas of the user,each holder will preferably be provided with more sets of notches e and7 than are in use for teeth at any one time. By so providing extranotches the user can, by a proper selection of notches, space the teethas desired.

D indicates the rake-teeth that are secured in place by the holder, suchteeth being formed, as usual, of heavy spring wire, and each having theordinary turned part at its upper end, which turned partgenerally knownin the trade as a tooth lateralis indicated in the drawing by D. Asstated, a number of the holders B will be employed on a single rake inorder to secure all of the rake-teeth in place, such holders beingarranged end to end along the angleiron head. The edges of the twoflanges c and cl bear against the inner face of the wall A of such head,and the upper part of the wall 6 of the holder where it bends to formthe flange c bears against the wall A of the head.

E indicates securing bolts for attaching the holder to the wall A, thenuts on the bolt being indicated by g. WVhen the holder is secured inplace by these bolts and nuts the several teeth held thereby will extendthrough the notches e and f in the flanges 0 and d, respectively, andthe tooth laterals will be inclosed or housed in the triangular chamberformed by the downwardly inclined flange a of the holder and the wallsA, A of the angle-iron head. Fitting in such housing or inclosure thelaterals are held against rattling or wabbling but are free to have aslight turning or hinge-like movement when the teeth are sprung ,bymeeting an obstructio WVith the parts in position it will be seen thatthe edge of the inclined flange bears not only against'the wall A of theangleiron head but also against the securing bolts E. Such aconstruction insures great strength and very effectively resists anytendency to crush or distort the holder due to excessively tightscrewing of the nuts on the bolts, for, as will be appreciated, such 1operation of the rake.

That which I claim as my invention, and desire to secure by LettersPatent is.

1. The combination with an angle-iron rake-head, of a tooth-holdercomprising a channel-bar having a notch in each of its flanges toreceive a tooth, said flanges having their edges bearing against theangleiron, and means for securing said channelbar against one wall ofthe angle-iron, one of the flanges of the channel-bar being inclinedtoward said securing means.
